About the role We’re looking for a skilled and solution-driven Java Developer to join our Returns team. You’ll help build and evolve the heart of our post-purchase tools – allowing e-commerce websites to offer a smooth returns mechanism and help us ensure it runs reliably at scale. This is a hands-on role where you’ll be involved in everything from design and development to testing, deployment, and monitoring.

About you You’re a team player who thrives in collaborative environments but also enjoy working independently when needed. With a structured and solution-oriented mindset, you like solving complex challenges and producing clean, high-quality code. Communication, curiosity, and a positive attitude are key strengths you bring to your work.

Responsibilities

· Design, develop, test, and release backend features for Returns in line with team and company guidelines.

· Build and maintain integrations with e-commerce platforms (e.g. Shopify, Magento, Centra) — including webhooks, authentication, and data imports.

· Contribute to architecture and platform decisions (security frameworks, GDPR, architecture, monitoring, CI/CD tools).

· Write clean, testable, and reusable code that is scalable and cost-efficient.

· Work with modern practices such as code reviews, automated testing, and continuous integration/delivery.

· Be an active member of an autonomous team, helping shape both the product and how we work.

· Stay up to date with new technologies and proactively suggest improvements for performance and scalability.

Required professional experience

We are looking for both junior and senior backend engineers with experience in most of the following technologies:

· Java

· Spring Boot and the Spring ecosystem (Spring Data JPA / Hibernate)

· PostgreSQL, including schema migration tooling (Liquibase or Flyway)

· AWS (S3, SES, and related services)

· CI/CD knowledge such as Jenkins, Bitbucket Pipelines, Docker, etc.

· Monitoring tools such as ELK stack or equivalent

· Testing: unit testing (JUnit, Mockito), integration testing against mocked external services (WireMock, REST Assured), and performance testing (e.g. JMeter)

Nice to have:

· Designing and versioning public REST APIs (OpenAPI / Swagger)

· Redis and caching strategies

· E-commerce or post-purchase domain experience

For senior candidates, we additionally value experience working in a large, long-lived codebase — carving out and building modern services alongside a monolith, and driving modernization without disrupting a system that merchants rely on every day.

What we’re looking for in you

· Strong problem-solving skills with the ability to deliver clean and scalable code.

· Service-minded with a positive, proactive attitude.

· Comfortable working independently as well as in a collaborative agile team.

· Fluent in written and spoken English.

Why join us?

At nShift, you’ll work on a platform used globally to handle millions of deliveries, solving complex technical challenges with real-world impact. We value knowledge sharing, autonomy, and continuous learning, offering plenty of opportunities to grow your skills while contributing to meaningful projects.

Och den förändringen öppnar för spännande utmaningar där gamla invanda sätt att jobba utmanas. Det betyder också att vi måste hålla oss i konstant utveckling. På riktigt. Både som individer och som verksamhet. Vi behöver föra samman innovation och digitalisering i en härlig kombination, där vi tillsammans kan hitta de där smarta och praktiska lösningarna som kunderna knappt vet om att de behöver. Än.

Ditt team och arbetsplats

Du blir en del av ett team med seniora utvecklare som arbetar nära varandra i vardagen. Här finns både erfarenhet och en tydlig struktur för hur arbetet drivs framåt.

Arbetet sker agilt med dagliga standups och ett gemensamt ansvar för leveranserna. Samtidigt har du utrymme att ta ansvar för dina delar och driva arbetet framåt, med stöd från teamet.

Teamet samarbetar även med kollegor i andra delar av organisationen, bland annat inom test och internationella team. Kulturen är öppen och inkluderande, med ett arbetssätt där man stöttar varandra och gärna delar med sig av sin kunskap.

Mer om dig

För att lyckas i rollen har du flera års erfarenhet av utveckling i C#/.NET samt arbete med databaser, gärna MS SQL. Du är van att arbeta i komplexa IT-miljöer och känner dig trygg i att hantera både legacy-system och nyutveckling. Du arbetar strukturerat, tar ansvar för det du levererar och har förmåga att göra genomtänkta avvägningar kring tekniska lösningar framåt. Som person är du noggrann, lösningsorienterad och flexibel, med ett naturligt driv att hitta hållbara vägar framåt. Du trivs i samarbete med andra, delar gärna med dig av din kunskap och bidrar till en kultur där teamet tar gemensamt ansvar. Du kommunicerar obehindrat på både svenska och engelska i tal och skrift. Erfarenhet från finans- eller försäkringsbranschen är meriterande, men viktigast är att du motiveras av möjligheten att vara med och bygga lösningar som ska hålla över tid.
